High-fiber diets with reduced crude protein for commercial layers
Provedor de dados: 89
Autores: Praes,MFFM; Junqueira,OM; Pereira,AA; Filardi,RS; Duarte,KF; Sgavioli,S; Alva,JCR; Domingues,CHF.
This study aimed at evaluating diets containing different fiber sources and two crude protein levels on the performance, egg quality, and nitrogen metabolism of commercial layers. In total, 392 48-wk-old Isa Brown layers were distributed according to a completely randomized experimental design in a 3x2+1 (control) factorial arrangement, resulting in seven treatments with seven replicates of eight birds each. Treatments consisted of three fiber feedstuffs (cottonseed hulls, soybean hulls, and rice hulls) and two dietary crude protein levels (12% and 16%). Cottonseed hulls associated with the high crude protein level (16%) resulted in the worst feed conversion ratio per dozen eggs. Diets with 16% crude protein resulted in the highest feed intake, egg...

ABSTRACT Currently, agro-industrial by-products have increasingly been used in animal feeding, as they constitute an alternative source of nutrients for the animal diet and a way to simultaneously reduce environmental pollution. The objective of this study was to examine increasing levels of inclusion of coconut cake in Japanese quail diets in the laying phase on their production performance and egg quality. A total of 360 Japanese quails were allotted to eight treatments with nine replicates and eight birds per experimental unit, in a randomized-block design. Five diets were formulated: a diet without inclusion of the by-product; and diets containing 3, 6, 9, and 12% coconut cake. The experiment lasted 63 days, with evaluations occurring at every 21 days....

Performance and carcass characteristics of free-range broiler chickens fed diets containing alternative feedstuffs
Provedor de dados: 89
Autores: Faria,PB; Vieira,JO; Silva,JN; Rodrigues,AQ; Souza,XR; Santos,FR; Pereira,AA.
The present study was carried out to evaluate the effects of alternative feedstuffs as partial substitutes of corn and soybean in free-range broiler diets on performance, carcass yield and technical-economic viability. A total of 400 Pescoço Pelado broilers were distributed in a completely randomized experimental design (CRD), with four treatments (treatment 1:Control; treatment 2: 10% rice bran inclusion; treatment 3: 10% ground cassava leaves; and treatment 4: 10% ground lead tree hay) with four replicates per treatment. Each replicate consisted of a group of 25 birds per paddock, separated per sex. Initial weight (IW), final weight (FW), body weight (BW), daily weight gain (DWG), feed intake (FI) and feed conversion ratio (FCR) were evaluated. Carcass,...

Small intestine development of laying hens fed different fiber sources diets and crude protein levels
Provedor de dados: 89
Autores: Praes,MFFM; Pereira,AA; Sgavioli,S; Duarte,KF; Alva,JCR; Domingues,CH de F; Puzzoti,MM; Junqueira,OM.
The objective of the presente study was to evaluate the effects on different dietary fiber sources and crude protein levels on the intestinal morphometry of commercial layers. Isa Brown® layers with 48 weeks of age were distributed in a completely randomized experimental design with a 3 x 2 + 1 factorial arrangement, resulting in seven treatments with seven replicates of eight birds each. At the end of the fourth experimental period (28 days each), birds were 64 weeks of age and were randomly chosen (two birds per replicate, totaling 14 birds per treatment), weighed and sacrificed by neck dislocation. Their intestine was dissected and the duodenum, jejunum and ileum were collected for subsequent analysis of intestinal morphometry. Treatments consisted of...
